Abstract

A telemetry system for monitoring a rejection reaction of a transplanted organ being transplanted within a patient's body is provided. The telemetry system includes (a) a telemetry control unit located outside the body of the patient; and (b) a telemetry monitoring unit implanted within the body of the patient, the telemetry monitoring unit including: (i) at least one acoustic transducer being for receiving an acoustic signal from the telemetry control unit and converting the acoustic signal into a first electrical signal, the at least one acoustic transducer further being for receiving a second electrical signal and converting the second electrical signal into a transmitted acoustic signal receivable by the telemetry monitoring unit; and (ii) a plurality of electrodes positionable in intimate contact with, or deep within, the transplanted organ and being in communication with the at least one acoustic transducer, the plurality of electrodes being for passing the first electrical signal through the transplanted organ for monitoring the electrical impedance thereof and further being for relaying the second electrical signal corresponding to the electrical impedance to the at least one acoustic transducer so as to enable the monitoring of the presence or absence of the rejection reaction.
